I recentley aquired a .61 size super custum aero engine. I fired her up on duraglow 5 and was not impressed with her performance...Can anyone tell me the recomended fuel for this type of engine......As at the moment I seem to be having black gunk which is appearing and no visable smoke from engine.....either when leaned in or out on needle valve....Oh and recomended glow plug for her Hot or cold.....

Many thanks

Hope to hear form you soon.... :stupid:
